vertically guided in the lower jaw 8, these toothed racks being arrangedon both ends of the jaw, and actuated by means of spur wheels 195, 196meshing with the said toothed racks and keyed upon a shaft 198 journaledin the lower jaw and provided with a crank 197. As readily seen byrotating the crank in one direction or in the other, the clamping devicemay be opened or closed the upper jaw being parallelly guided. After thewarp threads have been clamped in the clamping device 8, 8, the end ofthe warp is wound upon the thread clasp suspended from the end of thewarp and the clasp is secured to the thread clamping device 8, 8 forinstance by putting it into hooks 199 provided on the clamping jaw 8.

The machine A is carried and guided by a guide rod 10 supported at itsend in the side walls 2, 3 and by a prismatic guide 11 which forinstance is rigidly connected with the clamping jaw S. The guiding iscompleted by the driving shaft 12 rotatably mounted in the lateral walls2, 3 and which imparts the working motion to the various parts of themachine and produces the shifting of the machine across the warp. To thelast mentioned end a crank 13 the stroke of which may preferably bevaried is secured to one end of the shaft 12. This crank is connected bya link it witl an oscillating lever 15 which carries a spring controlledpawl 16 adapted to be engaged and disengaged, and is freely mounted on astud 17 secured in the lateral wall 3 of the framework of the machine.The stud 17 also carries rotatably a ratchet wheel 19 rigidly connectedwith a worm 18. The latter meshes with a worm wheel 20 keyed upon acrank shaft 21 carrying a crank 22 and arranged at right angles withreference to the shaft 12. The worm wheel 20 is loosely mounted on theshaft 21 (Fig. 1*) and may be coupled therewithby means of a couplingdisk 20 rigidly secured to the shaft 21 and provided with holes 20adapted to be engaged by a spring controlled engageable anddisengageable pin 200 mounted on the worm wheel 20; this pin may also beprovided with means for securing it in its disengaged position. Securedto shaft 21 is a sprocket j wheel 23 over which runs a chain 24;conveyed on the opposite side of the machine over a sprocket wheel 25having the same diameter, the warp leasing machine A being inserted inthe upper part of the chain 24.

and Figs. 15 to 17 show another embodiment of the thread clampingdevice, Fig. 15 being i a front elevation view; Fig. 16 a partial top 1plan view and Fig. 17 a vertical cross section of same.

The framework of the machine comprises i two lateral walls rigidlyconnected together, 2, 3 (Figs. 1 and 2) and provided at their frontsides with slot bearings 4 adapted to receive the journals of the warpbeam 5 carrying the warp G. The latter is conveyed over a breast beam 7arranged at the front and above, on the lateral walls 2, 3 and be in theform of a roller, to a clamping device 8. The latter is adapted to holdthe entire width of the warp and is secured to the lateral walls behindthe leasing device of the warp leasing machine A which may be shifted inthe well known manner in the framework of the machine in an obliquedirection to the warp. In order to avoid the repeated insertion andfixation of the ends of the warp threads in the clamping device, theclamping device 8 is preferably constructed in such amanner that it isadapted to receive the thread clasp which is permanently secured in thewell known manner to the end of the warp. Tension is imparted to thewarp 6 after the clasp has been inserted into the machine clampingdevice 8, by rotating the warp beam 5 in the direction of the arrowsshown by the drawing and fixing the journals of the warp beam in thebearings 4: by means of set screws 9. The upper movable jaw 8 of theclamping device 8 is preferably arranged in such a manner that itsrising and lowering motions take place parallelly to the stationary jaw.Such a form of construction of the clamping device has been shown byFigs. 15 to 17. In this device the jaws 8 and S are provided withlongitudinally fluted clamping portions 190, 191 adapted to allow of thewarp being tightly secured. The uniform tension of the warp threads isthen obtained by means of a brush roller 192, Fig. 1, which is rotatablymounted behind the framework of the machine. The warp after having beensecured at its end in the usual clasp remaining in a permanent mannerupon it, is drawn between the open clasping device 8, 8 and put over thebrush roller 192 which is then rotated and thus exerts a uniformtraction on all the warp threads which thus are uniformly tensioned.Hereafter the thread clamping device 8, 8 is closed and the warp isclamped in a tensioned condition as the warp had been previouslyprevented from rotating in the above described manner so that thetension cannot be released during the working.

The opening and closing of the clasping device is effected by means oftoothed racks 193, 194: secured to the upper jaw 8 and The adjustabilityof the stroke of the crank 13 on shaft 12 may for instance be secured byarranging the crank pin 26 on a nut 27 mounted in the crank arm so as tobe adapted to rotate but not to be shifted, the said nut 28 beingadapted to be locked in position after adjustment by a locking screw 29passing through the crank pin 26. It is necessary to provide adisengageable coupling between the shaft 21 and the worm wheel 20 inorder to allow of the machine A being rapidly brought back by means ofthe crank 22 after the leasing of the warp has been finished. Owing tothe disengageable arrangement of the pawl 16 the coupling device may bereleased from the ten stance by means of spring controlled lockingdevices. On the opposite side of the machine, the shaft 12 carries afixed pulley 31 and a loose pulley 32 adapted to receive a driving belt.The drive may however be performed in any other desired manner forexample directly by a motor.

The disengaging of the machine is effected after each achievement of awarp, either by hand or by the machine A itself which acts upon anadjustable arm of the disengaging device after having traveled over theentire width of the warp.

The lease holding means are in the embodiment shown formed by leasethreads 33, 3a which are unwound from stationary bobbins 35, 36 passedthrough eyelets 3', 88 and drawn in the form of loops by slides S9, 10(Fig. 7) and the ends of which are secured in a stationary clasp 4:1 orin any other suitable manner. lVith a view of ren dering the threadloops not too large, the loops are preferably passed again throughthread guides 42' It will be found suitable to secure the clasp -11 tothe lower part of the claim 2st so that during the work of the machinethis clasp is always moved in the opposite direction to that of themachine. Owing to this arrangement the lease cords or threads arereleased in the proportion to the advancing motion of the machine andthus are saved.

The slides 39, at) provided with the eyelets S7, 38 for the leaseholding means 83, 34 are guided in suitable guides above and below thewarp in the framework of the machine in a plane which is parallel to thewarp threads and perpendicular to the waip plane. They are moved inopposite directions. The slides 39, 10 are actuated by pnslr ing rodsintroduced from above and from below into their guide ways and of whichthe pushing rods 43, 4A take between themselves the slide 39 and thepushing rods 15, t6 the slide 40 (see Figs. 3 and t). The guide ways ofthe slides 39 and 10 are interrupted at the height of the plane of thewarp and the upper and lower pushing rods only move to the vicinity ofthe warp, while the motion of the slides above or below the warp iseffected by other means. The pushing members for the slides 39, 40 arecon nected together in pairs with a view of moving them in oppositedirections (see also Figs. 13 and let). Thus the two pushing members 13and a5 situated above the warp are connected by links 47, 48 with thearms 49, 50 of a three armed lever 19, 50, 51 which may be oscillated ona stationary pivot 52 secured to the machine frame, while links 53, 5-1connect the pushing members and 1-6 arranged below the warp, with arms55, 56 of the three armed lever 55, 56, 57 which also may be oscillatedon a stationary pivot 58 secured to the framework of the machine. Thearm 51 of the three arm-ed lever -19, 50, 51 is connected by aconnecting rod 59 with the arm 60 of an angle shaped lever 60, 61 whichis adapted to escillate on a stationary pivot 62 of the framework of themachines and the other arm (51 of which is hingedly connected with theupper end of the vertical connecting rod 6? the lower end of which isconnected with the arm 64 of an angle lever (34:, 65 adapted tooscillate 011 a stationary pivot 66 of the framework of the machine andthe arm 65 of which is connected by a connecting rod of with the arm 57of the three armed lever 55, 56, 57. A connecting rod ()8 which at 69 isconnected with the connecting rod and grasps at its upper end of thecrank pin 70 of the crank disk '71 secured to a shaft 72 which isrotatably mounted in the framework of the machine, connects theconnecting rods 63 with the crank disk 71. The latter is rigidlyconnected with a spur wheel 73 which continuously meshes with a spurwheel 74 adapted to loosely rotate on the main shaft 75 of the machine.The ratio of multiplication between the spur wheels 73 and 7 L is 1:2.The spur wheel 7-} is rigidly connected with a ratchet wheel 76 adaptedto be engaged by a spring controlled counter pawl 77 the object of whichis to prevent backward rotation, as well as by a spring controlled pawl78. The latter is rotatably mounted on the free end of an oscillatingarm 79 and is provided with an arm 80 adapted to disengage the pawl inthe manner to be described later on, if it is not desired to produce thechange of the lease carrying means, when no thread has been conveyed tothe leasing device. The oscillating arm 79 receives motion from aneccentric 81 the stroke of which has been calculated in such a mannerthat the actuating pawl 78 at each stroke ratchet wheel 76 to rotatewhereby the crank disk ratio of multiplication of rotated by 180.

The drive of the main shaft 7 5 is effected a quarter of a tour 71 oving to the 1:2 is each time causes the i from the shaft 12 by means ofspur gear wheels 82, S3 of equal dimensions the first of which isadapted to be slid on the shaft 12 while being prevented from rotatingthereon, the latter spur gear wheel being rigidly secured to the mainshaft of the machine.

Each complete stroke of the crank disk '71 is followed by a change ofposition of the slides 39 and 10 adapted to be moved in oppositedirections so that. always one of them isbelow and the other above thewarp 0. However, as the pushing members receive by the crank disk 71from. either side a motion going not so far as the plane of the warplifting means are still necessary which are arranged above and below theplane of the wap and are adapted to act upon the means for changing theposition of the lease holding means in such a manner that they transportthe said means independently from the pushing members from the one orthe other side on the opposite side of the warp plane. The embodimentshown by the drawings for this purpose comprises for each slide 39 andit) a pair of driving hooks 84-. 85 and S6, 87 respectively also Figs.13 and 14) adapted to be oscillated on stationary pivots 88, 89, 90 and91 arranged on the framework of the machine and of which those which aresitu ated above and those which are situated below the warp areconnected together by means of links 92. so as to force them to movesimultaneously toward one another. Each of the driving hooks of theupper and of the lower pair is actuated from the main shaft 75 of themachine. Thus the driving hooks S 1 and 85 have received the shape oftwo armed levers one of the arms of which (9 1 and 95 respectively) isconnected by a connecting rod 90 and 97 respectively and an angle lever98, 99 having its fulcrum at- 100 and angle lever 101, 102 with thefulcrum at 103 with the opposite ends of a con neeting rod 104 providedabout in its middle portion with a loop 106 surrounding an cecentric 105on the main shaft 75 so that during the rotation of the shaft 7 5 theconnecting rod 101 alternately receives an ascending and a descendingmovement. The

driving hooks 85 have inclined working surfaces 107 acting like wedgesupon the proj ecting eyelets provided on the slides 39 and 40 andconsequently force the slides 39, %0 to continue their motion in thesame direction in which they previously had received their motion by thepushing members.

In order to render impossible the change of position of the leaseholding means when no thread is to be leased the actuating pawl i 78 isrendered in this case ineffective by disengaging it from the ratchetwheel 70 when the actuating arm '79 moves upward. To this end a movableabutment 10S adapted to be adjusted by a thread feeler is brought intothe path of the arm of the pawl 78 so that the arm 80 is stopped and thepawl forced to perform a rotary motion on its pivot 109 at the end ofthe actuating arm 7 9 thus disengaging the pawl from the ratchet wheel76. The movement of this abutment 108 into its working position isperformed by coupling it with a continuously moved member by means of acarrying on hook rigidly connected with a thread feeler, the latter andthe carrying on hook being rigidly connected with the movable abutment108.

In the embodiment shown by the drawings, the movable abutment 108 isprovided with an arm 111 which is extended beyond its fulcrum 110 and isconnected by a link 112 with an arm 113 arranged on a hollow shaft 11stwhich is ournaled in the machine so as to be parallel to the threads ofthe warps. The arm 113 is constantly acted upon by a spring 115 theopposite end of which is secured at 11.6 to the framework of the machineand forcesthe abutment 108 constantly into its position of rest shown inplain lines by Fig. 5. Secured to the other end of the hollow shaft 114-is an arm 117 Y which at its lower end is angularly bent between themeans for changing the position of the lease holding means and carriesat its front end an angle lever 119, 120 (Fige) adapted to be oscillatedon a bolt 11S and the arm 119 of which is downwardly directed andprojects downwardly beyond the plane of the warp, while the other arm120 which is more horizontally arranged, has received the shape of ahook. The crank lever 119, 120 may oscillate on pivot 118 itsoscillation being however limited so that when the crank lever occupiesits position of rest, the arm 119 thereof is directed perpendicularlydownward. The limitation of the said oscillations is effected by anextension 121 provided on the crank lever 119 120 and adapted to abutagainst apin or the like 122 secured to the arm 117.

The hollow shaft 114i contains a rotatable spindle 123 which by theshaft 7 5 receives at each working course of the machine an oscillatorymotion through an eccentric 124- connecting rod 125 and lever arm 126.Secured to the other end of said spindle 128 is an arm 127 whichsimilarly to arm 11'. is engaged with an angular bend between the meansfor changing the position of the lease holding means the said arm 127being provided at its free end with a projection 128 which is directedtoward the arm 117 and adapted to be engaged by the carrying on hook 120when the feeler 119 is not moved by a warp thread transported across themachine. in such a manner that it raises the carrying on'hook 120, thatis to say when it once happens that a warp thread is missing. Owing tothe coupling which is then produced between the arm 117 and the continu=ously reciprocated arm 127, the arm 117 also receives an oscillatingmotion which brings the abutment 108 above the arm 80 of the pawl 78 sothat the latter is disengaged from the ratchet wheel 76 when theactuating arm 79 is raised (see Fig. 6).

Through change of the position of the lease holding means, effected eachtime, after the leasing of a warp thread, one time the one and the nexttime the other lease hol'ding means is brought above the leased threadwhereby the lease is formed. It is however essential for the securityand good working of the machine that each time only a single warp threadis leased and to this efiect means must be provided which are adapted toallow with certainty the separation from the remaining warp threads ofthat thread which is about to be leased at each operation of themachine. These means, as the machine must be adapted to be applied toall kinds of warp and warp threads of any thickness, must be adapted tobe controlled so as to be suitable for the thickness of the warp threadsabout to be treated.

In general, in order to render possible the separation of a singlethread from the warp, by the machine which is moved across the latter,it is first necessary to force the warp threads which are immediately infront of the leasing tools, into the plane of the warp and one at theside of the other. To this end device has been provided which smoothesthe warp threads while simultaneously increasing their tension so thatthreads which perhaps would be superposed or crossing, are ranged sldeby slde. For this purpose a curved receiving surface 129 rising abovethe plane of the warp is secured to the framework of the machine thisreceiving surface projecting in the direction of travel of the machinein front of the leasing tools. The free end of this receiving surfaceprojects below the plane of the warp so that when the machine movesforward the warp threads travel upon the receiving surface 129 and aregradually raised by the latter whereby their tension is by little andlittle increased. This operation already ranges the warp threads one bythe side of the other. However in order to avoid in any case anysuperposition of warp threads a pressure plate 130 arranged in front ofthe leasing tools and moved against the receiving surface 129temporarily exerts pressure on the warp threads while at the same timeor alternately a smoothing of the warp threads in front of the leasingtools is performed by smoothing members 131 moved toward the end of thewarp. These smoothing members131 may for instance be arranged on avrotary carrier 132 mounted on a shaft 133 journaled in the framework ofthe machine and carrying a spur gear wheel 134 which constantly mesheswith a larger spur gear wheel 135. The latter is rigidly connected witha ratchet wheel 136 having for instance six teeth and is rotatablymounted together with the latter on a peg 137 secured to the frameworkof the machine. The ratio of multiplication between the spur gear wheels135 and 134 is 3 to 1 so that at each rotation of the wheel 135 by onesixth of a revolution, the wheel 134 is rotated by one half of arevolution. Now, as the carrier 132 which is connected with the wheel134 has two smoothingmembers 131 arranged in diametrical opposition, oneof the two smoothing devices acts upon the warp threads at each rotationof the wheel I 135 by one sixth of a revolution.

The ratchet wheel 136 is engaged by a spring controlled counter-pawl 138preventing it from rotating backward, as well as by a spring controlledpawl 139 pivotally connected at 141 to an arm 140. The arm 140 isadapted to oscillate on a pivot 142 secured to the framework of themachine and is connected by a connecting rod 143 with the arm 144 of anangle lever 144, 145 adapted to be oscillated on pivot 62 secured to theframework of the machine, the lever 144, 145 receiving its motion fromthe main shaft 75 by means of an eccentric 146 the rod 147 of which ispivotally connected with the arm 145 of the crank lever144, 145.

For moving the pressure plate 130 against the warp and the receivingsurface 129 any desired suitable means may be provided. In the exampleshown by the drawings, the pressure plate 130 is carried by a lever 148which is adapted to freely oscillate on the shaft 137 and is providedwith an angularly directed arm 149 directed toward the carrier 132 ofthe smoothing members 131. This arm 149 projects into the path of camsor pegs 150 two of which are arranged in diametrical opposition on thecarrier 132. In the relative arrangement, shown by the drawings, of thesmoothing members with reference to the cams 150 pressure is exertedupon the warp threads by the pressure plate 130 at the beginning of thesmoothing action. In order to hold the smoothing members for a greaterlength in contact with the warp threads and at the same time exert uponthe latter during the whole smoothing action a pressure which is asuniform as possible, the smoothing mem bers 131 may be yieldinglymounted on their carrier or rather one may, as in the arrangement shownby the drawings, provide under the smoothing members a bearing surfaceor plate 151 for the warp thread which is yieldingly secured to theframework of the machine. The plate 151 is for instance yieldinglyconnected at one of its ends by a flat spring 152 with the framework ofthe machine. Its upper surface is arranged so p as to be level with thehighest part of the reeeiving surface 129.

. The end of the receiving surface 129 which is directed toward theleasing tools as well as the corresponding end of the pressure plate 130are preferably provided with notches which guide the tools for theindividual separation of the threads which freely lie over the notch.These notches are most clearly shown by Figs. 9 to 11.

The device for separating the warp thread about to be leased from theremaining threads which device may also be employed for the same purposein other machines for instance in warping machines comprises an abutment153 serving as a stop for the warp thread to be leased and which with aview of allowing the warp thread to be leased to continue its motiontoward the leasing tools, is movably arranged and to this end mountedfor instance on an arm 154- secured on an oscillating shaft 155journaled in the frame work of the machine above the plane of the warp.Movably arranged in front of the abutment 153 and at a distancecorresponding to the thickness of the warp threads to be leased is aseparating knife 156 which passes immediately along the opposite side ofthe warp thread to be leased and securely applied against the abutment153, and thus separates this thread from theremaining warp threads. Theknife 156 may have any suitable form and receive any suitable motionperpendicularly to the plane of the warp, the width of the knife bladebeing parallelly arranged to the warp threads.

In the embodiment shown by the drawing the knife 156 has received theform of a sickle and is secured to an arm 157 which is rigidly securedto a spur gear wheel 158 and is rotatably mounted on a stud 159 securedto the framework of the machine above the plane of the warp. With thespur gear wheel 159 meshes a toothed segment 160 rigidly secured to thearm 1 10 oscillating on the pivot 142. Consequently an oscillatingmotion is imparted to the spur gear wheel carrying the knife 156 at eachworking period of the machine. At the beginning of the downward motionof the knife between the warp threads, the abutment 153 occupies itsworking position (Figs. 3 and 9). But as soon as the thread to be leasedhas been separated by the point of the knife from the remaining threadsand it is necessary to transport it farther toward the leasing tools,the abutment 153 must be removed from its working position. This may beobtained by the action of a spring, while the reverse motion 71. e. thatwhich brings it into its operative position, is effected forcibly. It ishowever advantageous to have both motions of the abut-ment effectedpositively, as this is the case in the example of execution shown in thedrawings. To this effect the arm 15 1 carrying the abutment 153 isrigidly connected with a spur gear wheel 161 which constantly mesheswith a toothedsegment 162 which oscillates on a pivot 163 secured to theframework of the machine and is rigidly connected with an arm 164extending beyond its fulcrum. This arm 164 carries a pin 165 engaging acurved slot provided in aplate 166 which I is rigidly connected with thearm 140. The curved slot of the plate 166 is so shaped that while thepin 165 slides in the upper part 167 or in the lower part 168 of thecurved slot no motion is imparted thereto, and that a motion of the pin165 and consequently a rotation of the toothed segment 162 around thepivot in the one or the other direction only takes place when the pin165 slides in the middle part 169 of the curved slot. In order to enablethe device for separating the thread to be leased to be adjusted for anythickness of warp thread which is likely to be met with, the abutment153 may be adjusted with reference to the knife 156 according to thethickness of the warp threads of the warp to be treated in each case.This adjustment is preferably performed by means of a micrometric screw170 especially shown by Fig. 8 in longitudinal section. The set screw171 has for its object to secure each time the abutment 153 in itsadjusted position. The thread to be leased and engaged between themovable abutment 153 and the knife 156, must now be introduced betweenthe lease holding means which occupy their receiving positions after theabutment 153 has been removed by the above described means from itsworking position and been brought by them into a position wherein itallows the free passage to the separated threads. To this effect, thethread engaged by the knife is first gradually separated by a pushingdevice from the remaining warp threads and is conveyed to means adaptedto transport it farther.

The pushing device or member is formed by a wedge surface 172 which isadvantageously rigidly connected with the knife 156 and is arranged onthat side of the latter. which faces toward the lease holding means,this wedging surface entering into action when the motion of the knifeis continued in the same direction as before...

The thread is thereby pushed on a pair of wings or ribs 173, 174 rigidlymounted into the framework of the machine. During its travel the threadis prevented from accidentally jerking upward by a fork 175 arrangedabove it and equally secured to the framework of the machine. Betweenthe ribs or wings 173, 17-1 moves a fork shaped engaging member 176which is secured to the free end of a lever 177. The latter is hingedlyconnected to an arm 178 secured to an oscillating shaft 179 journaled inthe framework of the machine. This shaft 179 carries on its opposite endan arm 180 which is connected by a link 181 with the arm 182 of a cranklever 182, 184 oscillating around a stationary fulcrum 183 and the otherarm 18-1 of which is connected to the rod 185 of an eccentric 186secured to the main shaft 75 of the machine (see Figs. 4, and 7).

The lever 177 is provided with a curved slot 187 engaged by a guide pin188 rigidly mounted to the framework of the machine, the said slot beingslightly inclined downward nearly on its entire length from its frontend to its rear end while it is suddenly obliquely directed upward atits rear end at 187*.

With a view of grasping the separated warp thread which had beenadvanced toward. the grasping members 176 the latter is firstly movedinto its extreme right hand position (Figs. 4; and 10) by the abovedescribed means and by the oscillation of the arms 178 in the directionof the arrow shown by Fig. 4. In this position the guide pin 188 engagesthe rear end of the curved slot 187 wherefrom it follows that thegrasping member 176 is slightly lowered in this position, while duringthe reverse motion of the arm 178 the member 176 is first slightlyraised and engaged behind the thread which it is desired to grasp bymeans of its fork. During the further motion of the grasping member, inthe opposite direction to that indicated by the arrow of Fig. 1, thethread engaged by the grasping member is carried on (Fig. 11) andbrought behind the ribs 178 and 17 1 which at their ends form hookshaped notches 189. The thread then places itself behind the saidnotches and is held stationary by them. As soon as this has taken place,the changement of position of the lease holding means is performed inthe manner described above (position shown by dotted lines in Fig. 12),so that these means are ready for receiving the next thread.

The function of the machine summed up is as follows: At the beginning ofthe work the stepped machine moved into its extreme left hand positionby means of the. crank 22 after the pawl 16 has been disengaged with theaid of the disengaging lever 30 and after the coupling of the worm wheel20 with the shaft 21 has been released. Hereafter the warp beam 5carrying the mrp G is engaged into the bearings 1 of the lateral walls 3and the end of the warp secured in the clasp is drawn over the breastbeam 7 through the open-ed clamping device 8, 8 and over the brushroller 192. The warp beam 5 is prevented from rotating and the warpuniformly tensioned over its entire width by the rotation of the brushroller 192 whereafter the warp is grasped by closing the clamping device8, 8. Thus the insertion of the warp into the machine is terminated whenthe device shown by Figs. 17 is used. it is still necessary to wind theend of the warp on the clasp secured thereto and to put the clasp on theclamping device 8, 8 with a view of removing the end of the warp fromthe working path of the machine. After the lease threads 33, 34. havebeen threaded through the eyelets 37, 38 of the slides 39,-l0 and aftertheir ends have been secured in the clasp 11, the machine may be startedby throwing the shaft .12 in gear, engaging again the pawl 16 andcoupling the worm wheel with the shaft 21.

As soon as the machine reaches the warp owing to the advancing motionimparted to the machine by the pawl 16 and the ratchet wheel 19, thefirst threads of the warp ascend the receiving surface 129, theirtension being thereby gradually increased. Finally the threads arriveunder the pres sure plate 130. The latter which at each advancing strokeand consequently at each working period of the machine is once presseddown against the warp threads upon the receiving surface 129, as well asthe simultaneous action of the smoothing members 131 over the yieldingsupporting surface 151, force the warp thread to juXtapose themselves sothat they are arranged in front of the separating device and lie allparallelly side by side in the same plane.

As soon as the first thread has advanced near the movable abutment 153,it is separated from the remaining warp threads by the knife 156 whichdescends behind it. Thereafter the abutment 153 leaves its workingposition (Figs. 3 and 9) and goes into its position of rest (Fig. 10)while the knife 156 continues moving and causes the wedge shaped pushingmember 172, which is secured thereto to act upon the separated threadand to convey it behind the grasping fork 175 which in the meanwhile hasbeen brought into its receiving position. llereafter follows the motionof this fork in the direction opposed to that indicated by the arrow inFig. 10, whereby the upwardly directed end 187 of the curved slot 187causes first an upward motion of the fork which allows the latter tograsp the thread which has been delivered to it (Fig. 11). The fork 176continuing its motion in a direction which is opposed to that indicatedby the arrow, Fig. 10, carries the thread on and conveys it between thelease holding means 33 and 3 1- and also behind the notches 18$}.returned into its position of rest and the abutment 153 has againresumed its working position so that the following warp thread may beseparated at the next advancing motion of the machlne. After thegrasping In the meanwhile the knife 156 has member 176 has returned intoits position of rest (Figs. 9 and 12) the position of the lease holdingmeans is changed (position shown by dotted lines in Fig. 12) so thatthese means are also in position ready for receiving the next warpthreads to be leased.

The change of the lease may be effected because the thread which hasbeen leased has carried with it the feeler 119 during its travel throughthe machine, and thus has caused the carrying on hook connectedtherewith to leave the path of the extension 128 of the disengaginglever 12'? so that the locking lever is held by the spring in itsposition of rest (shown in full lines by Fig. 5), the pawl 78 remainingengaged with a view of giving the ratchet wheel 76 the necessary partialrotation and thereby transmitting the necessary rotary motion to thecrank disk 71 which has to produce the change of position of the leaseholding means. If however at the next working period of the machine theknife 156 is not yet adapted to reach the next thread and to separate itfrom the remaining threads the machine works without actuating a threadand if the change of position of the lease holding means were nowperformed, the lease would be disturbed, if in this case no provisionwere made for stopping the change of position of the lease holdingmeans. As already described above, this stopping is performed by thethread feeler 119 conserving its vertical position, whereby the carryingon hook 120 connected with it, is adapted to engage the extension 128 ofthe disengaging lever 127 so that the lever 27 carries with it the lever117 and thus forces the locking lever 108 against the action of thespring 115 into its locking position (shown by dotted lines in Figs. 5and 6) so that it disengages the pawl. 78 in the manner above describedand shown by Fig. (3, and thusstops the change of position of the leaseholding means. As soon as the separating means separate a new threadfrom the warp and convey it to the lease holding means, the change ofposition of the latter is again performed so that they again remainready for receiving the following thread until the next thread haseffectively been leased.

When the entire warp is leased the lease holding means are knotted onboth sides of the warp or if desired replaced by lease rods. Hereuponthe clamping device 8, S is opened and the end of the warp is wound uponthe warp beam. after the set screws 96 have been loosened. In the placeof 5 the finished warp, a new warp beam inserted into the machine in"the manner described after the machine had been brought back in themanner described into its initial position at the left hand of themachine. These lease holding means, in the present instance the leasethreads, are conveyed from the bobbins through the thread guides and theeyelets at the slides 39, L0 and back through the thread guides to thestationary clasp ll (which may also be secured to the lower part of thechain 24:) and the leasing of the new warp may begin.
